Technical Field
[0001] This invention relates to apparatuses and methods for applying a covering film to
a book.
Background Art
[0002] Adhesive covering films for books are widely available. In most cases these are applied
manually by removing a release paper covering the adhesive, carefully positioning
the book against the adhesive surface of the film, applying the adhesive film to the
front and back covers and spine, taking care to avoid or eliminate bubbles, and finally
trimming off the excess film.
[0003] This procedure is time consuming for large numbers of books, making it inefficient
for libraries, booksellers or publishers wishing to cover large numbers of books at
the same time. Experience shows that a skilled worker can typically cover 38-60 books
per hour with this method.
Disclosure of the Invention
[0004] There is provided an apparatus for applying a covering film to a book, the book having
front and rear covers and a spine, the apparatus comprising:
a gate mechanism having open and closed states, which in the closed state presents
a front surface against which a covering film may be overlaid whereby the spine of
a book may be pressed onto the covering film overlaying the front surface, and which
in the open state admits the book to a space rearward of the gate beyond the front
surface such that the book draws the covering film into said space; and
a laminating mechanism positioned rearwardly of the gate, the laminating mechanism
operable to receive a book admitted beyond the gate, and to apply pressure against
said film onto the front and rear covers of the book to cover the book with the film.
[0005] By presenting a front surface which can be used to support a covering film, and against
which the spine of a book can be pressed to sandwich the covering film between the
spine and the front surface, the book can be quickly positioned correctly on the (typically
adhesive) covering film. Then by the simple mechanism of opening the gate and admitting
the book into a laminating mechanism beyond the gate, we ensure that the covering
film, already in position against the spine (and adhered to it if the film is adhesive-coated),
is fully laminated to the book's front and back covers.
[0006] In contrast to the rate of 38-60 books per hour which a skilled worker can achieve
using manual methods, machines according to the invention can process over 300 books
per hour.
[0007] Preferably, the laminating mechanism comprises at least a first roller and a second
roller operable in combination to receive the book and to apply pressure against said
film onto the front and rear covers thereof as the book passes between the rollers.
[0008] A motor may be provided to drive at least one roller. There can be a linkage for
driving both rollers from a common motor. Alternatively each roller may have its own
respective motor. Again alternatively, only one roller may be driven, the other being
caused to turn by the pressure of the book against it as the book is moved by the
driven roller.
[0009] In one embodiment, the gate mechanism comprises a pair of doors each hinged at a
respective outer edge, wherein in the closed state the doors meet at a respective
inner edge, and wherein in the open state the doors hinge rearwardly about their outer
edges to admit the book into said space between said inner edges.
[0010] In another, currently preferred embodiment, the gate mechanism comprises a pair of
doors which when in the closed state meet at a respective inner edge, and which are
arranged to slide apart resulting in a gap between the respective inner edges to admit
the book therebetween.
[0011] The doors, in either case, preferably provide a continuous and substantially unbroken,
flat surface with any gap between the doors being of a size substantially smaller
than the width of a conventional book, i.e. the gap being less than 5 mm, more preferably
less than 2 mm, more preferably less than 1 mm. Such a surface acts as a flat table
against which the book may be compressed onto the covering film before the doors are
opened.
[0012] There is preferably a guide mechanism which receives a book and presents the spine
of the book onto the front surface.
[0013] More preferably, the gate mechanism comprises a pair of doors which when in the closed
state meet at a respective inner edge, and wherein said guide mechanism is positioned
relative to the pair of doors to present the spine of the book onto the adjacent inner
edges of the doors.
[0014] Preferably, the guide mechanism comprises first and second plates biased against
one another to retain the book when introduced between the plates, while allowing
the book to be pushed through and beyond the plates when the gate mechanism is open.
[0015] An apparatus as claimed in claim 10 wherein the plates are biased together to form
a generally Y-shaped guide mechanism, the stem of the Y-shape being formed by abutting
surfaces of the two plates, and the upper branches of the Y-shape being respectively
formed by an angled portion of each plate.
[0016] As an alternative to angled plates, the plates can be curved along some or all of
their height so that they flare away from one another to provide a guide into which
the book can be admitted.
[0017] In one embodiment, when the gate mechanism comprises a pair of doors which when in
the closed state meet at a respective inner edge, the inner edges moving apart when
the gate is in the open state, the first and second rollers can each be mounted on
a respective one of the pair of doors rearwardly thereof adjacent the inner edge of
the respective door.
[0018] Preferably, in this case, the first and second rollers are biased against one another
when the doors are closed, meeting at a point in line with the meeting point of the
inner edges of the doors, and when the gate is in an open state each roller moves
under a biasing force beyond the inner edge of the door on which it is mounted.
[0019] A gate motor is preferably provided for opening said gate. Where there are a pair
of doors, there can be a respective pair of gate motors such that each gate motor
drives a respective one of said doors to open said gate.
[0020] Alternatively, where the gate comprises a pair of doors, the apparatus may further
comprise a linkage for driving both doors from a common gate motor. This arrangement
is currently preferred as a very precise and synchronised opening of the doors can
be achieved, with the gap increasing uniformly on either side of a centre line as
the doors open, which assists in admitting the book and cover reliably to the laminating
mechanism.
[0021] There is preferably a controller for activating the or each gate motor and the or
each roller motor in synchronicity.
[0022] The apparatus may further include a film supply mechanism for receiving a roll of
covering film such that a length thereof may be drawn across said front surface in
advance of a book being received. In this embodiment, the film can then be cut to
a suitable length before or after the book is pressed onto the film and before the
gate is opened.
[0023] Alternatively, the covering film may be supplied in lengths and individual lengths
can be simply placed into position.
[0024] Preferably, the apparatus further comprises a stop structure adjacent said gate on
the front said thereof, said stop structure allowing alignment of an edge of said
film with a face of said book.
[0025] There is also provided a method of applying a covering film to a book, the book having
front and rear covers and a spine, the method comprising:
providing a gate mechanism having open and closed states, which in the closed state
presents a front surface against which a covering film may be overlaid whereby the
spine of a book may be pressed onto the covering film overlaying the front surface,
and which in the open state admits the book to a space rearward of the gate beyond
the front surface such that the book draws the covering film into said space;
providing a laminating mechanism rearwardly of the gate, the laminating mechanism
operable to receive a book admitted beyond the gate, and to apply pressure against
said film onto the front and rear covers of the book to laminate the film against
the front and rear covers;
placing a cover film to overlay said front surface;
pressing a spine of a book onto said cover film overlaying the front surface;
opening the gate to admit the book to said space such that the book draws the covering
film into said space; and
laminating the film against the front and rear covers with said laminating mechanism.
[0026] Preferably, the film is adhesive on some or all of one side thereof, the adhesive
side being placed facing away from the front surface, and the adhesive being a pressure
adhesive, wherein the laminating process applies pressure to adhere the film to the
front and rear covers.
[0027] Preferably, the laminating mechanism comprises a pair of pressure rollers which receive
the book and compress the film against the front and rear covers.
[0028] Preferably, the film is adhesive on some or all of one side thereof, the adhesive
side being placed facing away from the front surface, and the adhesive being heat
activated, further comprising the step of heating the film as part of the laminating
process to adhere the film to the front and rear covers.
[0029] When the adhesive is heat activated, the laminating mechanism can comprise a pair
of pressure rollers which receive the book and compress the film against the front
and rear covers, where the rollers are heated.

Detailed Description of Preferred Embodiments
[0031] In Fig. 1 there is indicated, generally at 10, an apparatus for applying a covering
film to a book. The apparatus is embodied in the general form of a cabinet 12 having
a work surface or front surface 14, with operator controls 16 on a face 18 of the
cabinet, and a guide and stop assembly 20 located above the front surface.
[0032] The guide and stop assembly has three main elements: a left-hand guide plate 22,
a right-hand guide plate 24, and a back stop structure 26. The guide plates are biased
towards each other to provide a generally Y-shaped guide into which a book can be
introduced from above.
[0033] The guide plates each have a cut-away so that a gap 28 is defined between a pair
of legs 30,32 which extend from the guide plates down into the cabinet 20 where the
biasing mechanism is situated. As a result of this gap's existence, the work surface
or front surface 14 is largely unobstructed over the majority of its area.
[0034] The front surface 14 is composed of the upper faces of two sliding doors 34,36 whose
operation will be described further below. On each door, a stop plate 38 is mounted
which is aligned vertically with the face of the back stop structure 26 (only the
stop plate 38 on the right-hand door 36 is indicated by reference numeral). Due to
this alignment, it will be appreciated that a covering film (which is assumed to have
a straight edge) can be overlaid on the front surface 14, abutting against the pair
of stop plates 38. Then a book can be introduced, spine first, between the guide plates
22,24 (forcing them apart) while abutting against the stop plate 26. Pushing the book
down onto the covering film will result in an aligned covering film which is squared
relative to the book's axis. (It may be preferred that the stop plates 38 are recessed,
relative to the back stop structure 26, by a millimetre or two, in which case the
covering film will extend beyond the edge of the book by a corresponding amount. While
this gives a greater margin of error for an operator, it results in a requirement
to trim the film along this edge, as discussed further below.)
[0035] Referring now to Fig. 2, the mechanism can be seen in schematic cross section, taken
in a plane parallel to the surface of the back stop structure seen in Fig. 1, i.e.
transverse to the plane along which the guide plates 22,24 meet.
[0036] In Fig. 2 we can see the guide plates 22,24 each have an angled structure, so that
when biased together (as indicated by the dotted arrows) they form a generally Y-shaped
guide mechanism, the stem 40 of the Y-shape being formed by abutting surfaces of the
two plates, and the upper branches 42,44 of the Y-shape being respectively formed
by an angled portion of each plate 22,24. There is no reason why other shapes could
not also be used to guide a book into a desired position, which is aligned with a
meeting point 46 between the two sliding doors 34,36 which together provide the front
surface 14.
[0037] The terms "front" and "forward", as opposed to "rear" and rearward", as used herein,
denote the directions outside and inside the doors 34,36, respectively. Thus the guide
plates 22,24 are forward of the front surface 14, while the two laminating rollers
48,50 seen in Fig. 2 are rearward of the doors 34,36 and the front surface 14.
[0038] As seen in Fig. 2, a covering film 52, has been placed in position, overlaying the
front surface 14. The covering film may be, for example, an adhesive coated polyester
film of known type, which is supplied in standard sizes with a release liner protecting
the contact adhesive. In use the adhesive is exposed by removing the release liner,
and the film 52 is placed, adhesive side up, on the front surface, generally centred
over the line 46 where the doors meet, and with one edge abutting against the stop
plate 38 (Fig. 1). The alignment of the cover against the back stop is precise and
easily achieved, while the requirement to generally centre the cover over the mid
line 46 is less critical -the positioning only needs to be as accurate as is required
to ensure that enough film extends on either side to cover half the spine and either
the rear or front cover of the book 54. Typically, the covers will be from a few millimetres
to (preferably) a few centimetres bigger in each direction than the combined width
(front cover 56 + spine 58 + back cover 60) and the height of the book.
[0039] Fig. 3 shows the next stage of operation, with the book 54 pressed fully down onto
the covering film 52, which is thus sandwiched between the book's spine and the front
surface 14 of the abutting doors 34,36. Due to the biasing force on the guide plates
22,24, the book is precisely aligned over the line 46 where the doors 34,36 abut.
[0040] Fig. 4 shows the apparatus just after the operator has engaged one of the controls
16 (i.e. a "start" button) which actuates both a gate motor (not shown) and a pair
of roller motors (not shown). A single gate motor is used to drive apart the doors
and thereby open a gap 66 below the spine of the book 54. By using a precise linkage,
the motion of the two doors can be tied, so that the inner edges 68 are always the
same distance from the centre line. One could, alternatively, have a pair of gate
motors. A set of bearings 60 is provided for each door 34,36 to support it in smoothly
sliding open/
[0041] Each of the laminating rollers is driven by its own motor, in the direction indicated,
such that they will pull a book engaging with them from a forward to a rearward direction.
Biasing spring force on the rollers ensures that they exert pressure against a book's
covers as they draw it rearwardly.
[0042] In Fig. 5, the gate (doors 34,36) has opened beyond the thickness of the book 54,
allowing the operator to push the book rearwardly of the front surface 14. As the
spine had already adhered to the covering film 52, it is pulled evenly rearwards towards
the laminating rollers 48,50 which catch the edges of the spine at the moment captured
in Fig. 5.
[0043] As shown in Fig. 6, the rollers are forced apart by the book and they drive the book
rearwardly, simultaneously compressing the adhesive surface of the covering film 52
(which continues to be drawn in by the book 54) and adhering the film to the book's
front and rear covers 56,60. In Fig. 6 the gate is fully open and the doors are no
longer moving. The maximum gap can be fixed at a size big enough to accommodate most
commercially produced books, or it can be adjustable by the operator for a given batch
of books.
[0044] It will be noted that throughout the process shown in Figs. 2-6, the vertical alignment
of the book is controlled by the biasing force provided by the Y-shaped guide 22,24
and the roller 48,50. Once the book is free of the guide and of the rollers, it drops
below the rollers for further processing such as by dropping onto a conveyor belt
leading to a trimming station.
[0045] Figs. 7 and 8 show a covered book 54 which has been covered with film 52 by the machine
of Figs. 1-6. It can be seen that the film 52 is flush with the top edge 62 of the
book due to the previously discussed stop structure 26 and stop plates 38 (Fig. 1).
At the other edges (bottom edge 64 and fore edge 70) the film 52 extends beyond the
book's edges. Therefore the final step is to trim the book and cover using a guillotine
or dedicated trimming machine along the trimming lines 72 identified in Fig. 8. In
this way, a millimetre or so is sacrificed along each edge to achieve a sharp edge
where the film is flush with the edges of the books' front and rear covers and spine.
[0046] Figs. 9-11 show an alternative embodiment, using similar views to those of Figs.
2, 4 and 6. However, the embodiment of Figs. 9-11 differs in two major respects. Similar
parts to the earlier embodiment are indicated with reference numerals that differ
by 100 (e.g. book 154 vs. book 54).
[0047] Firstly, the gate and front surface 114 are provided by doors 134,136 which are each
hinged along an outer edge 138 (Fig. 9). The doors hinge rearwardly when the operator
actuates the controls (after the book 154 has been pressed onto the covering film
152 overlaying the front surface 114), a gap 166 develops due to the hinging action
of the doors.
[0048] Secondly, the laminating rollers 148,150 are mounted on to the rearward side of the
doors, adjacent the inner edges 168. The rollers 148,150 are carried on brackets 180
which are spring loaded and biased towards each other. Thus it can be seen that as
the doors begin to open (Fig. 10), the rollers remain in contact with each other.
Then in Fig. 11, the rollers have moved sufficiently to project beyond the inner edge
of each door and thereby engage with and press against the book's covers 156,160 to
laminate the book and, due to the motors, draw it rearwardly past the doors.
[0049] The invention is not limited to the embodiments disclosed herein which can be varied
